6mm GURPS wargame

[Azinctus]

In my Warhammer 40K campaign I've been using Games Workshop's epic figures and some GHQ 1/285 WWII models to run huge GURPS fights.

In one battle we had the same village modelled in 6mm and 28mm setup on two tables and switched from one scale to the other as the PCs and their platoon of Imperial Guard entered the village. As they snuck around the 28mm streets of the village sniping at the defenders, they had to keep an eye on the 6mm hills on the other table because there was an enemy tank looking to give fire support.

For the rules I decided to stick to GURPS as written, with some acceleration for bases of soldiers. A stand of five men gets to move or shoot, and if it shoots it fires once at max aim bonus. Effectively we imagine that they are all aiming for three rounds then firing, giving a cadence of one aimed shot per five seconds, the extra second is lost in ducking, reloading, talking or resting. Obviously that doesn't make much sense if they move then fire, but no one seemed to mind that. Heavy weapons, machine guns and cannons, are based separately and use the normal rules, for those I printed aim tokens so we can easily see who has aimed.

Damage roles are replaced with a an amour save and penetration modifiers pinched from Warhammer. Damage is noted with counters, each counter roughly representing a man down and giving the stand -1 to hit and leadership tests to not flee or be suppressed (stunned).

I haven't tried to use these systems for large actions. The biggest battle was a Stalingrad-style defense of an apartment block in a city. The PCs and their platoon faced waves of 3-4 armoured vehicles and 10 stands of infantry. At the same time as they negotiated with the civilians in the cellar and tried to steal their money. A battlemat served as the 28mm interiors while the big table had the city laid out using cardboard buildings.

Movement is a little fiddly, a typical five yard move is only five millimetres and GURPS armours penetration rules for armoured vehicles seems wrong to me, but while Steel Panthers and Squad leader seem more realistic, I haven't been in many tank battles.

Where I really like this system is that we get to see tactical combat happening at ranges of 100+metres.

I have pictures (not great, I'm no photographer), sketchy rules and printable tokens and range ruler. Anyone interested? Got some tips? Tried something similar?

My pal wants to use a similar plan to setup a pitched fantasy battles.
